What is banana powder for? Was the question I asked my friend and she told me it is a great solution to an oily complexion, which I tended to have. Anyway, all the hype is true and it really does help keep a shiny complexion under control. It is also good as it lasts all day and evens skin colour. Banana powder is an affordable product and will appeal to anyone who is searching for a concealer that evens skin tone and keep greasy skin under control. It is easy to get hold of just order from Amazon. It is a product that really does do what it says it does.
